One of the main components of this circuit is LDR

A Tutorial on How to make a Touch alarm / Touch sensor circuit that latches the output whenever our skin (finger) or any object with negative charge gets in.

A Hall Effect Sensor or magnet sensor is used to detect if the door is open and close. It's output connected to the base of the transistor BC547 which is responsible to provide a path to 555 timer IC. A buzzer and an LED are connected on Pin 3 of 555 for indication of alarm. Finally, we have connected a 9v Battery to power the circuit Here is a simple and cheap Laser Based Security System, which costs below Rs. 100. It is a simple circuit using LM358 OP-AMP and LM555 Timer. This circuit is triggered when the Laser beam falls on the LDR interrupts, which sounds the buzzer connected to it. This can be used to protect your valuable items, money, room etc.

The circuit is very simple and using only few easily available components. The heart of the circuit is a famous 555 timer IC. The circuit is using a pendulum system, which can be easily made easily with wires by making a loop with one wire and attaching a weight with another wire Referring to the above shown laser activated GSM call security circuit, we can see that the IC 555 is configured as a standard astable. The 555 astable is powered through a delay OFF timer circuit which is in turn attached with an LDR trigger. The LDR is supposed to be focused with a laser beam aligned across the restricted zone But when you move the laser away, the alarm should go off again. If everything is working properly, solder it all together on a printed circuit board. The board that I used is a general purpose IC board. These are really convenient for circuits that are built around small ICs like the 555 timer. I also used an IC socket to attach the IC The siren is supplied by the IC3 timer with a delay depending on the C3 capacitor. The IC4 turns off the alarm sound and the circuit backs to the start condition. By using the values indicated in the schematic (C3 and C4) the circuit should work with a time delay of 10-15 seconds SECURITY ALARM CIRCUIT WITHOUT USING 555 TIMER voltage and it is low. IC 2) IR Transmitter: The output of 555 timers is low when input voltage at pin The operating voltage of transmitter is around two to 3V, to four is high, then 555 timer produces the frequency which drop the remaining voltage and we connect a resistor in series with IR led.

Focus the Laser diode/light on the LDR and you will see the L.E.D and Buzzer going OFF If you interrupt the laser light focusing on the LDR the circuit will trigger and the alarm will ring! Congrats! Your Laser Security Alarm System is now ready Only if the alarm can tolerate 9V. I go along with using an SCR as a simple latch, which has only three connections. You just turn off the power to reset the SCR. The laser circuit would trigger the SCR, which would turn on the alarm sounder. The SCR has a volt or so drop when on, so would likely work better with a 9V power source Water Level Alarm Using 555 Timer: This is a similar project we have done already but here we are using a different module 555 timer circuit.
